Specification of Letters Patent.

Patented May 9, 192-2.

Application filed March 18, 1921. Serial No. 453,303.

To all whom it may concern:

Be it known that T, AnoLrH FRANKJEL, a citizen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Machines for Settlng Snap Fasteners, of

which the following is a specification.

The object of my invention is to provide means to assemble complemental members of snap fasteners upon cloth or other desired material, to cause the prongs of one member to pass through the material and through the other member and to be clenched against said member.

Myinvention comprises a machine havmg spaced guideWa-ys for the members of the snap fastener, means to separately propel said members along said guideways, an

means to cause the prongs of one member to pass through the other member and to be clenched against the latter member upon the operation of a plunger.

My invention also comprises novel details of improvement that will be more fully hereinafter set forth and then pointed out in the claims.

Reference is to be had to the accompanymg drawings forming part hereof, where- Fig. 1 is a longitudinal section on line 1, 1 in Fig. 2; Fig. 1 is a detail section n line 1 1 in Fig. 1; Fig. 2 is a plan view of Fig. 3; Fig. 3 is a vertical section on line 8, 3 in Fig. 1; Figs. 4, 5 and 6 aresections on lines 4, 4,5, 5, and 6, 6, respectively, of Fig. 1; Fig. 7 is a view substantially similar to Fig. .3, showing the parts in as sembling position; Figs. 8 and 9 are detail horizontal sections substantially on the lines 8, 8, and 9, 9, respectively, in Fig. 3;'F1g. 10 is a detail view substantially similar to Fig. 8, parts being omitted; Fig. 11 is a fragmentary perspective view of part of the guiding means for the pronged member of the snap fastener; Figs. 12 and 13 are perspective views of the members of the snap fastener; Fig. 14: is a detail v1ew illustrating the assembled fastener members, and Fig. 15 is a section on line 15, 15 in Fig. 1 1.

Similar characters of reference indicate corresponding parts in the several views.

Numeral 1 indicates the base of the machine which has a longitudinal guideway 1 to guide the members A of the snap fastener. The guideway 1 has a central open portion for the passage of the projections a of members A and recessed portions 1 upon which the base parts a of said members are guided The members A are placed in the guideway 1 with the projections a dependmg and said members are fed in series by means of a spring 2 that pushes a slide memher 3 along a guide-rod 1 detachably mounted in the base (Fig. 1). Rod 4 has a head 5 fitted in an opening 6 in the base, said head being provided with a projection 7 to bear against the base to lock the rod in position against the pressure of spring 2. By rotating the head 5 the rod and the spring with the slide 3 may be removed and released when the supply of members A are to be fitted to the guideway 1 A stop 8 onrod 1 limits the movement of slide 3. At the inner end of guideway 1 the recessed parts 1 are formed curved at 1, in the nature of an anvil, to cause clenching of the prongs b of the staple-like clamp members B of the snap fastener (Fig. 3). The prongs b may be stamped from the metal of the members B. Members A have slots or openings a through which the prongs b are passed to be clenched against the base portion of said members (Fig. 15). The member or other article C is stopped in assembling position by an abutment 9 at the adjacent end of guideway 1 (Figs. 1 and 8).

Above guideway 1 is an armor member 10 having a longitudinal guideway 11 to receive the fastener members B with their prongs Z) adapted to travel in slots 11 of said guideway with the base portions 7) of said members resting upon the ledges 11 of the guideway, (Fig. 5). The arm 10 is shown pivotally supported at 12 upon base 1, and maybe normally raised from the base by a spring 13 shown coiled upon pivot 12 and hearing at one end against the base and at the other end against arm 10. The members B are fed forwardly by means of a spring 1d shown coiled around a rod 15 located in guideway 11 and having a slide 16 pressed by the spring against a row or series of members B in the guideway. Rod 15 is shown provided with a head 17 having a projection 17 which head operates in an opening 18 at the end of guideway 11 and may be withdrawn by rotating said head,

A to be fastened to the cloth ing the projection 17 retaining the rod in place in the guideway by abutting against a stop 19 at the end ofthe guideway, (Fig. 1). A head 20 on rod 15 limits movement of slide 16. The end-most member B (Fig. 1) abuts against a stop 21 carried by arm 10 to cause registering of the prongs Z) of member B with the slots (6 of member A beneath the endmost member B. The stop 21 is shown made adjustable whereby the prongs b may be caused to properly register with the slots a of member A. The stop 21 is shown retained in position by a screw 22 meshing in a threaded hole in a support 23 on arm 10 (Fig. 1). The abutment or stop 21 is re cessed vertically in opposition to a corresponding recessed end of arm 10 providing a vertical passage 24 for members B (Figs. 1 and 6).v The upper portion of the inner surface of abutment 21 and the correspondsurface of recess 241 at the end of arm 10 are made slightly indented at 25 to provide a ledge upon which the end portions of the members B will hang to be pushed toward the members A beneath the same (Figs. 6

and 11). Arm 10 is provided with a vertical guideway 25 receiving a plunger 26. A jection 27 on the arm 10 is slidable in a guideway 28 in plunger26, whereby plunger 26 is slidably retained from rotating. A spring 29 shown coiled around plunger 26, bearing at one end against head 26 on plunger 26 and at the other end against arm 10, serves normally to raise the plunger, the projection 27 limitingupward movement. of the plunger by engaging the metal at the lower endof guideway 28 3). The lower end of the plunger is adapted to engage members B to push them toward men bers A through the fabric C, the lower end of plunger 26 being shown enlarged at 26 to bear upon members B over their prongs b. A lever 30 is shown pivoted on member 10 at 31 and provided with an opening 32 receiving up-right portion 10 of arm 10, said lever having projections or screws 33 oper ating in slots 34 in said member and engaging plunger 26. The upward movement of the plunger is limited by the screws 33 engaging the metal atthe upper ends of slots 34-, and the downward movement of the lever pushes the plunger to drive members B through fabric C and members A, and clench prongs b.

When my improved machine is, to be used a supply of members A, B, is placed in the respective guideways 1 11, with the slides 16 and 3 pushing said members to be stopped at the abutments 9 and 21 respectively. Arm 10 is raised and the fabric or the like is placed upon the base 1 in the required position over the member A at abutment 9. Arm 10 is then lowered to rest upon the fabric and lever 30 is depressed, causing plunger 26 to descend to push the endmost member B from guideway 24, to cause its prongs b to pierce the fabric C and to pass through the slots a of member A, the anvils 1 causing the prongs b to be clenched against the base portion of member A to clamp the fabric between the members A, B of the fastener, (Figs. 7, 14, and 15). Member 10 will be raised to permit withdrawal of fabric C having the snap fastener member attached.

My invention provides a simple and efii cient machine for expeditiously and cheaply attaching snap fasteners of the class speci-' fied tofabric. l Vhile I have illustrated the member A as one member of a snap fastener it will be understood that the member B may be used for attaching a different fastener member to the fabric. The member A may be considered the male member of the fastener adapted to cooperate with a corresponding complemental female member.

Snap fasteners such as herein illustrated are shown in m U. S. Letters Patent No. 1,391,250, granted September 20, 1921, which are adapted to be attached to fabric by means of my improvements herein set forth.

While I have referred to the particular character of fastener members to be assembled on fabric it will be understood that my invention may be used to assemble members other than the particular snap fastener referred to, and that the details of construction set forth may be varied within the scope of the appended claims without departing from the spirit of my invention.

Having now described my invention, what I claim is 1. The combination of a base having a longitudinal guideway. means tending eonstantly to feed a plurality of members in the guideway, an arm over the base having a longitudinal guideway opposed to the first named guideway, means to feed members in the secondnamed guideway, said arm and base being movable relatively one to another to receive fabric therebetween, abutments at the ends of said guideways to re-' tain members over one another, and a plunger operative relatively to said guideways to push members from the second named guideway to members in the other guideway through the interposed fabric.
